This is what I am thinking. I will get the HDS 7 Gen3 and mount it on the front of my boat by the trolling motor. (I currently have an Elite 7 HDI there now) Mount the transducers on the back of the boat. Connect my 10 " tablet via the GoFree app to my HDS unit and BAM I now have a 10" HDS unit at the console. I have looked into sun shades for the tablet and mounting hardware and can get all that for less than $75. So I basically end up with 2 HDS units for the price of one.
